• a mount securely attached to said camera mechanism assembly, said mount being in the form of a cylinder having a first engagement member at an inner peripheral surface thereof;
• a space between an outer peripheral surface of said mount and an inner peripheral surface of said aperture;
• and
• an elastic member fitted into said space and imparting a uniform biasing force to the whole outer periphery of said mount so that the space becomes uniform around the whole outer peripheral surface thereof, thereby determining the position of said mount relative to said outer box;
• said interchangeable lens including a cylinder having a lens element fitted therein in contact with an inner peripheral surface thereof and having a second engagement member formed around an outer peripheral surface thereof, said cylinder of said lens being attached to said mount by engagement of said first engagement member with said second engagement member.

A waterproof camera system of the type comprising a camera mechanism assembly, a waterproof outer box in which is incorporated said camera mechanism assembly and a waterproof type interchangeable lens which is detachably mounted in said outer box, further comprising:

• an aperture formed through a wall of said outer box;
• an outer mount formed on said outer box and positioned near said aperture;
• a first elastic member disposed between said outer mount and said interchangeable lens in order to determine the position of said interchangeable lens relative to said outer mount by imparting a uniform biasing force to said outer mount;
• and
• a second elastic member positioned between said aperture and said camera mechanism assembly in order to determine the position of said camera mechanism assembly relative to said aperture by imparting a uniform biasing force to said aperture.
